What causes fault code GEN-VIB1 (Excessive Vibration Alarm)?

Motor or pump bearings failing — vibration increases as bearings degrade. Coupling misalignment between motor and driven equipment. Imbalance in rotating component — fan, impeller, or flywheel. Loose foundation bolts — equipment walking on base. Belt or chain whip from incorrect tension

How do I fix fault code GEN-VIB1?

Check vibration data — is it axial, radial, or both?. Radial dominant = imbalance. Axial dominant = misalignment.. Tighten all foundation/mounting bolts. Check coupling alignment with dial indicators or laser alignment tool. Check belt tension — too loose causes whip, too tight causes bearing load. If bearing-related, schedule bearing replacement before catastrophic failure. Trend vibration data — rising trend confirms degradation

Probable Causes (ranked)

Motor or pump bearings failing — vibration increases as bearings degrade
Coupling misalignment between motor and driven equipment
Imbalance in rotating component — fan, impeller, or flywheel
Loose foundation bolts — equipment walking on base
Belt or chain whip from incorrect tension

Fix Steps

1 Check vibration data — is it axial, radial, or both?
2 Radial dominant = imbalance. Axial dominant = misalignment.
3 Tighten all foundation/mounting bolts
4 Check coupling alignment with dial indicators or laser alignment tool
5 Check belt tension — too loose causes whip, too tight causes bearing load
6 If bearing-related, schedule bearing replacement before catastrophic failure
7 Trend vibration data — rising trend confirms degradation

Field Trick

Put a penny on top of the motor. If the penny bounces off, vibration is excessive and bearings are probably going. If it stays, vibration is within acceptable range.
